What is the Disaster Recovery System?The Disaster Recovery System (DRS), which can be invoked from, Cisco Unity Connection Administrationprovides full data backup and restore capabilities. The Disaster Recovery System allows you to perform regularly scheduled automatic or user-invoked data backups.

DRS restores its own settings (backup device settings and schedule settings) as part of the platform backup/restore. DRS backs up and restores drfDevice.xml and drfSchedule.xml files. When the server is restored with these files, you do not need to reconfigure DRS backup device and schedule.

Caution Before you restore, ensure that the version that is installed on the server matches the version of the backup file that you want to restore. The Disaster Recovery System supports only matching versions for restore. For example, the Disaster Recovery System does not allow a restore from version 6.1.(1).1000-1 to version 6.1(2).1000-1, or from version 6.1.(2).1000-1 to version 6.1(2).1000-2

Caution Before you restore Cisco Unity Connection, ensure that the hostname, IP address, version, and deployment type of the restore matches the hostname, IP address, version, and deployment type of the backup file that you want to restore.

The Disaster Recovery System includes the following capabilities:

• A user interface for performing backup and restore tasks.

• A distributed system architecture for performing backup and restore functions.

• Scheduled backups.

• Archive backups to a physical tape drive or remote SFTP server.

The Disaster Recovery System contains two key functions, Master Agent (MA) and Local Agent (LA). The Master Agent coordinates backup and restore activity with Local Agents.

Caution DRS encryption depends on the cluster security password. If you change this security password through the Command Line Interface or a fresh install, then it is recommended that you take a fresh backup immediately or remember the old security password.

Note When a Cisco Unity Connection cluster is configured, The Disaster Recovery System uses an SSL-based communication between the Master Agent and the Local Agent for authentication and encryption of data between the publisher and subscriber servers. DRS makes use of the IPSec certificates for its Public/Private Key encryption. Be aware that if you delete the IPSEC truststore(hostname.pem) file from the Certificate Management pages, then DRS will not work as expected. If you delete the IPSEC-trust file manually, then you must ensure that you upload the IPSEC certificate to the IPSEC-trust.

Task Lists for Backing Up and Restoring Cisco Unity Connection

Note The Disaster Recovery System also backs up the certificates files. Ipsec-cert, Ipsec-trust, Tomcat-cert, Tomcat-trust, Third Party CA certificates, Ipsec key and cert, and Root-cert are backed up.

Caution Schedule backups during off-peak hours to avoid call-processing interruptions and impact to service.

Task Lists for Backing Up and Restoring Cisco Unity ConnectionAdded November 16, 2010The following tables list the tasks for backing up and restoring Cisco Unity Connection.

Note DRS backs up and restores the backup device settings and backup schedule settings, so you do not need to reconfigure DRS settings after a restore.

System Requirements

System RequirementsRevised January, 2015If you are upgrading from release 5.1(3), you must download the appropriate patch file from Cisco.com, create an ISO image DVD from the patch file, then copy the contents of the DVD to a remote FTP or SFTP server that the server can access.

Cisco allows you to use any SFTP server product but recommends SFTP products that have been certified with Cisco through the Cisco Technology Developer Partner program (CTDP). CTDP partners, such as GlobalSCAPE, certify their products with specified version of Cisco Unified Communications Manager. For information on using GlobalSCAPE with supported Cisco Unified Communications versions, refer to:

http://www.globalscape.com/gsftps/cisco.aspx.

Cisco uses the following servers for internal testing. You may use one of the servers, but you must contact the vendor for support:

• Open SSH (refer to http://sshwindows.sourceforge.net/)

• Cygwin (refer to http://www.cygwin.com/)

• Titan (refer to http://www.titanftp.com/)

Cisco does not support using the SFTP product FreeFTPd. This is because of the 1 GB file size limit on this SFTP product.

Note For issues with third-party products, contact the corresponding vendor for support

Note While a backup or restore is running, you cannot perform any OS Administration tasks because Disaster Recovery System blocks all OS Administration requests by locking the platform API. However, this does not block most CLI commands as only the CLI-based upgrade commands use the Platform API locking package.

Tip Schedule backups during periods when you expect less network traffic.

Note Be aware that if you migrate to an HP DL380-G6 server (software-only), you will not be able to install older versions of Cisco Unified Communications Manager (5.x and 6.x) on the new server. Therefore, to be able to run a DRS backup, you must install the older version of Cisco Unified Communications Manager on your old publisher (which may no longer be supported). Once this backup has been completed, you will be able to restore it on your HP DL380-G6 (software-only) publisher.

How to Access the Disaster Recovery System

How to Access the Disaster Recovery SystemTo access the Disaster Recovery System, choose Disaster Recovery System from the Navigation drop-down list box in the upper, right corner of the Cisco Unity Connection Administration window. Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified Communications Operating System Administration.

Note You set the Administrator username and password during Cisco Unity Connection installation, and you can change the Administrator password or set up a new Administrator account by using the Command Line Interface (CLI). Refer to the Command Line Interface Reference Guide for Cisco Unifed Communications Solutions for more information.

Master Agent Duties and ActivationThe system automatically activates the Master Agent (MA) on the server.

The Master Agent (MA) performs the following duties:

• The MA stores systemwide component registration information.

• The MA maintains a complete set of scheduled tasks in an XML file. The MA updates this file when it receives updates of schedules from the user interface. The MA sends executable tasks to the applicable Local Agents, as scheduled. (Local Agents execute immediate-backup tasks without delay.)

• You access the MA through the Disaster Recovery System user interface to perform activities such as configuring backup devices, scheduling backups by adding new backup schedules, viewing or updating an existing schedule, displaying status of executed schedules, and performing system restoration.

• The MA stores backup data on a locally attached tape drive or a remote network location.

Local AgentsThe server has a Local Agent to perform backup and restore functions.

The Local Agent runs backup and restore scripts on the server.

Note When a Cisco Unity Connection cluster is configured, the Disaster Recovery System uses an SSL-based communication between the Master Agent and the Local Agent for authentication and encryption of data between the publisher and subscriber servers. DRS makes use of the IPSec certificates for its Public/Private Key encryption. This certificate exchange gets handled internally; you do not need to make any configuration changes to accommodate this exchange.

Managing Backup DevicesBefore using the Disaster Recovery System, you must configure the locations where you want the backup files to be stored. You can configure up to 10 backup devices. Perform the following steps to configure backup devices.


Managing Backup Devices

Note You can add, delete, and list devices through the Command Line Interface. For more information on CLI commands for DRS, refer to the “Command Line Interface” section on page 16.

Procedure

Step 1 In Cisco Unity Connection Administration, in the Navigation list, click Disaster Recovery System, and click Go.

Note When a Cisco Unity Connection cluster is configured, we recommend that you back up the publisher server and, optionally, the subscriber server.

The Disaster Recovery System Logon window displays.

Step 2 Log in to the Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified Communications Operating System Administration.

Step 3 Navigate to Backup > Backup Device. The Backup Device List window displays.

Step 4 To configure a new backup device, click Add New.

Step 5 To edit a backup device, select it in the Backup Device list. Then, click Edit Selected.

The Backup Device window displays.

Step 6 Enter the backup device name in the Backup device name field.

Note The backup device name may contain only alphanumeric characters, spaces ( ), dashes (-) and underscores (_). Do not use any other characters.

Step 7 Choose one of the following backup devices and enter the appropriate field values in the Select Destination area:

• Tape Device—Stores the backup file on a locally attached tape drive. Choose the appropriate tape device from the list. Note the following considerations:

– You cannot use more than one tape for a single backup. If you have more data than will fit on a tape, either you must store backups on a network directory, or you must back up components on one tape and back up mailbox stores on one or more additional tapes.

– You cannot store more than one backup on a tape; each backup overwrites the data from the previous backup, so you only have the data from the most recent backup. If you want to create more than one backup for a server (components in one backup, mailbox stores in another backup, for example), you must use separate tapes. Otherwise, you will only have the portion of the data that you backed up last.

Note Be aware that if you are logged in through a VMware virtual machine, you cannot back up on a tape. This is because the tape device option is disabled for VMware users.

• Network Directory—Stores the backup file on a network drive that is accessed through an SFTP connection. Enter the following required information:

– Server name: Name or IP address of the network server

– Path name: Path name for the directory where you want to store the backup file


Creating and Editing Backup Schedules

– User name: Valid username for an account on the remote system

– Password: Valid password for the account on the remote system

– Number of backups to store on Network Directory: The number of backups to store on this network directory.

If you are backing up more than one Connection server, we recommend that you create a separate directory on the network drive for each Connection server. In addition, if you are using DRS to back up other applications (Cisco Unified Communications Manager, Cisco Unified Presence), we recommend that you create a separate directory for each of the other servers. The value that you specify here applies to all of the backups in the directory, not just the backups for one server. For example, suppose you want to retain three backups for a Connection server and three backups for a Cisco Unified Communications Manager server. If you specify the same network directory for both servers, and if you specify three as the number of backups to store in the directory on both servers, only the most recent three backups will appear in the directory. If the last three backups were of the Connection server, you will not have any Cisco Unified Communications Manager backups at all.

Specify a value high enough to ensure that the backups you want to keep are not overwritten. For example, if you configure DRS so a full backup of a Connection server requires three separate backups (components, MailboxStore1, and MailboxStore2) and if you want to retain the two most recent full backups, choose 6 here. Choosing a lower number will cause the Disaster Recovery System to overwrite backups that you want to retain.

The location you specified in the Path Name field must have enough space for the number of backups you specify here plus one. When the network drive contains the maximum number of backups that you want to store, DRS saves the newest backup to that location before deleting the oldest backup.

Note You must have access to an SFTP server to configure a network storage location. The SFTP path must exist prior to the backup. The account that is used to access the SFTP server must have write permission for the selected path.

Step 8 To update these settings, click Save.

Note After you click the Save button, the DRS Master Agent validates the selected backup device. If the user name, password, server name, or directory path is invalid, the save will fail.

Step 9 To delete a backup device, select it in the Backup Device list. Then, click Delete Selected.

Note You cannot delete a backup device that is configured as the backup device in a backup schedule.

Creating and Editing Backup SchedulesYou can create up to 10 backup schedules. Each backup schedule has its own set of properties, including a schedule for automatic backups, the set of features to back up, and a storage location.

Note You can list and add backup schedules through the Command Line Interface. For more information on CLI commands for DRS, refer to the “Command Line Interface” section on page 16.


Creating and Editing Backup Schedules

Note Be aware that your backup .tar files are encrypted by a randomly generated password. This password is then encrypted by using the cluster security password and gets saved along with the backup .tar files. You must remember this security password or take a backup immediately after the security password change/reset.

Perform the following steps to manage backup schedules:

Procedure




Step 3 Navigate to Backup > Scheduler.

The Schedule List window displays.

Step 4 Do one of the following steps to add a new schedule or edit an existing schedule

a. To create a new schedule, click Add New.

b. To configure an existing schedule, click its name in the Schedule List column.

The scheduler window displays.

Step 5 Enter a schedule name in the Schedule Name field.

Note You cannot change the name of the default schedule.

Step 6 Select the backup device in the Select Backup Device area.

Step 7 Select the features to back up in the Select Features area. You must choose at least one feature.

Always choose to back up the following features:

• Recorded greetings and voice names (CONNECTION_GREETINGS_VOICENAMES).

• The database (CONNECTION_DATABASE).

• Other Connection-specific data (CUC).

Backing up messages (CONNECTION_MESSAGES_) is optional.

Step 8 Choose the date and time when you want the backup to begin in the Start Backup at area. Note the following:

• Schedule backups during off-peak hours to avoid affecting system performance.

• Do not schedule a backup to run while the Update Database Statistics task is running. By default, this task runs daily at 3:30 am.

Step 9 Choose the frequency at which you want the backup to occur in the Frequency area: Once, Daily, Weekly, or Monthly. If you choose Weekly, you can also choose the days of the week when the backup will occur.


Enabling, Disabling, and Deleting Schedules

Tip To set the backup frequency to Weekly, occurring Tuesday through Saturday, click Set Default.

Step 10 To update these settings, click Save.

Step 11 To enable the schedule, click Enable Schedule.

The next backup occurs automatically at the time that you set.

Step 12 To disable the schedule, click Disable Schedule.

Enabling, Disabling, and Deleting SchedulesProcedure

Note You can enable, disable, and delete backup schedules through the Command Line Interface. For more information on CLI commands for DRS, refer to the “Command Line Interface” section on page 16.




Step 3 Navigate to Backup > Scheduler.

The Schedule List window displays.

Step 4 Check the check boxes next to the schedules that you want to modify.

• To select all schedules, click Select All.

• To clear all check boxes, click Clear All.

Step 5 To enable the selected schedules, click Enable Selected Schedules.

Step 6 To disable the selected schedules, click Disable Selected Schedules.

Step 7 To delete the selected schedules, click Delete Selected.

Starting a Manual BackupFollow this procedure to start a manual backup.

Note Be aware that your backup .tar files are encrypted by a randomly generated password. This password is then encrypted by using the cluster security password and gets saved along with the backup .tar files. You must remember this security password or take a backup immediately after the security password change/reset.


Checking Backup Status

Procedure




Step 3 Navigate to Backup > Manual Backup. The Manual Backup window displays.

Step 4 Select a backup device in the Select Backup Device area.

Step 5 Select the features to back up in the Select Features area.

Always choose to back up the following features:


• The database (CONNECTION_DATABASE).


Backing up messages (CONNECTION_MESSAGES_) is optional.

Step 6 To start the manual backup, click Start Backup.

Checking Backup StatusYou can check the status of the current backup job and cancel the current backup job. To view the backup history, see the “Viewing the Backup and Restore History” section on page 14.

Caution Be aware that if the backup to the remote server is not completed within 20 hours, the backup session will time out. You will then need to begin a fresh backup.

Checking the Status of the Current Backup JobPerform the following steps to check the status of the current backup job.

Procedure




Step 3 Navigate to Backup > Current Status. The Backup Status window displays.

Step 4 To view the backup log file, click the log filename link.

Step 5 To cancel the current backup, click Cancel Backup.


How a Restore Affects Cisco Unity Connection Voice Messages

Note The backup cancels after the current component completes its backup operation.

How a Restore Affects Cisco Unity Connection Voice MessagesAdded November 16, 2010If you back up Connection, create one or more new mailbox stores, and then restore without backing up the new mailbox stores, the new mailbox stores are deleted.

If you back up and restore only the Connection directory, without also backing up and restoring Connection voice messages, some user folders may be deleted, depending on whether the associated features are in use for those users:

• The drafts folder is created the first time a user saves a draft message after the feature is configured. (You must either configure Connection to automatically save draft messages when users are disconnected or hang up, or configure Connection to allow users to save draft messages.)

• The future delivery folder is created the first time a user marks a message for future delivery. (Future delivery is not configurable.)

• The sent items folder, which allows users to recall messages they have already sent, is created the first time a user sends a voice message after message recall is configured. (In Cisco Unity Connection Administration, you must change the value of the Sent Messages: Retention Period (in Days) setting on the System Settings > Advanced > Messaging page to a value greater than zero.)

If the folders contain any messages, the messages are moved to the undeliverable messages folder.

Restoring or Replacing Cisco Unity Connection ServersIf you are restoring Cisco Unity Connection data on an existing server or on both servers in a Cisco Unity Connection cluster, do the procedure in this section.

If you are replacing a Cisco Unity Connection server or replacing the hard disks in a Connection server, including one or both servers in a Cisco Unity Connection cluster, start with the applicable task list in the “Replacing Cisco Unity Connection 9.x Servers or Hard Disks” chapter of the Reconfiguration and Upgrade Guide for Cisco Unity Connection Release 9.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/upgrade/guide/9xcucrugx.html. Each task list will redirect you to the procedure in this section to restore data.

Note Cisco Unity Connection does not support restoring or replacing clone cluster. Also, pre-configured backup devices must be created before restoring Connection servers.

Procedure

Step 1 If you reinstalled software on the server or on a Cisco Unity Connection cluster, do the following steps, as applicable:

a. Confirm that the IP address and host name of the server match the IP address and host name when the server was backed up. Otherwise, the restore will fail.


http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/upgrade/guide/9xcucrugx.htmlhttp://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/upgrade/guide/9xcucrugx.html

Restoring or Replacing Cisco Unity Connection Servers

In addition, if Cisco Unity Connection is running on a virtual machine, confirm that the following settings match the values when the server was backed up. The settings are used to create the license MAC value for the Connection virtual machine, and if you change any of them, you must get new license files for the virtual machine.

– Time zone

– NTP server

– NIC speed and duplex settings

– DHCP settings

– Primary DNS settings

– SMTP hostname

– X.509 Certificate information (Organization, Unit, Location, State, and Country)

b. Confirm that the Cisco Unity Connection version that is installed on the server exactly matches the Connection version that was installed when you made the backup.

For example, the Disaster Recovery System does not allow a restore from version 8.5(1).1000-1 to version 8.5(2).1000-1, or from version 8.5(2).1000-1 to version 8.5(2).1000-2. (The last parts of the version number change when you install a service release or an engineering special.)

c. Confirm that you have the security password that was in effect when the Cisco Unity Connection server was backed up.

DRS encrypts backed-up data by using the security password as the encryption key. If you changed the security password after the last backup, DRS will ask for the old security password.

d. Reinstall the licenses that were originally installed on the server.

e. If any Connection languages were previously installed, reinstall the same languages.

Step 2 On the Cisco Unity Connection server, sign in to Disaster Recovery System by using the same Administrator username and password that you use for Cisco Unified Communications Operating System Administration.

Step 3 Navigate to Restore > Restore Wizard. The Restore Wizard Step 1 window displays.

Step 4 Choose the backup device from which to restore in the Select Backup Device area. Then, click Next.

The Restore Wizard Step 2 window displays.

Step 5 Choose the backup file that you want to restore.

Note The backup filename indicates the date and time that the system created the backup file.

Step 6 Click Next. The Restore Wizard Step 3 window displays.

Step 7 Always choose to restore the following features:


• The database (CONNECTION_DATABASE): Restoring messages (CONNECTION_MESSAGES_) is optional.


Note The only features listed are the features that were included in the backup.

Step 8 Click Next. The Restore Wizard Step 4 window displays.


Restoring or Replacing Cisco Unity Connection Servers

Step 9 Select the Perform file integrity check using SHA1 Message Digest checkbox if you want to run a file integrity check.

Note The file integrity check is optional and is only required in the case of SFTP backups. You do not need to run a file integrity check when restoring from tape and local device backups.

Note Be aware that the file integrity check process consumes a significant amount of CPU and network bandwidth, which considerably slows down the restore process.

Step 10 When you are prompted to choose the node to restore, choose the same features that you selected in Step 7, and click Next.

Caution Existing data for the selected features is overwritten.

Step 11 To start restoring the data, click Restore.

Note If you selected the Perform file integrity check using SHA1 Message Digest checkbox in Step 7, DRS runs a file integrity check on each file when you click Restore. If the system finds discrepancies in any .tar file during the check, the restore process will ERROR out the component that failed the integrity check and move to restore the next .tar file (that is, the next component).

Step 12 To view the status of the restore, see the “Viewing the Restore Status” section on page 14.

Step 13 Restart the server. For more information on restarting, see the “System Restart” chapter of the Cisco Unified Communications Operating System Administration Guide for Cisco Unity Connection Release 9.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/os_administration/guide/9xcucosagx.html.

Step 14 If you are restoring a Connection standalone server, skip to Step 15.

If you are restoring a Connection cluster, force Connection to copy the data from the publisher to the subscriber server:

a. After the publisher server has finished restarting, log on to the command line interface for the subscriber server.

b. At the command line, run the following command to force Connection to copy data from the publisher server to the subscriber server:

utils cuc cluster overwritedb

c. Check the status of the Connection cluster on the subscriber server. At the command line, run the following command:

show cuc cluster status

d. Log on to the command line interface for the publisher server.

e. Check the status of the Connection cluster on the publisher server. At the command line, run the following command:

show cuc cluster status

Step 15 During off-peak hours, re-synchronize message-waiting indicators for each phone system:

a. In Cisco Unity Connection Administration, expand Telephony Integrations, and click Phone System.

b. Click the name of the first phone system.

Viewing the Restore Status

c. For Synchronize All MWIs on This Phone System, click Run.

d. Repeat Step a. through Step c. for the remaining phone systems.

Step 16 If you are servers or hard disks, return to the applicable task list in the “Replacing Cisco Unity Connection 9.x Servers or Hard Disks” chapter of the Reconfiguration and Upgrade Guide for Cisco Unity Connection Release 9.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/upgrade/guide/9xcucrugx.html.
